"Wake In Fright," dir. Ted Kotcheff, 1971. Sort of Deliverance-type story about a possibly suicidal teacher who spends a holiday in the rough n' tumble fictional town of Bundanyabba, where he's subjected to various indignities...includes a real kangaroo hunt, which isn't that tough to watch, but still not for the squeamish. A younger Donald Pleasance plays a pretty grimy character, possibly the highlight of the film. Check it out, I don't want to give away too much.
